Corynebacterium minutissimum is yet another member of the normal flora on human skin but it can be associated with the polymicrobial disease erythrasma. They are bacilli rod shaped and in some phases of life they are more particularly club shaped which inspired the genus name coryneform means club shaped.

Ck is a lipophilic corynebacterium.
Corynebacterium kroppenstedtii normal flora. As corynebacteriumspecies are found in normal flora they are usually considered contaminants from skin by microbiologists and surgical resection often remains the only treatment option. Genome sequence analysis of the c. Corynebacterium kroppenstedtii is an unusual member of this taxon as it lacks the characteristic mycolic acids in the cell envelope.
It usually is difficult to distinguish between infection colonization and contamination by isolated bacteria. By contrast our corynebacterium kroppenstedtii ck strain was isolated as monomicrobial culture. In the present study we analyzed formalin fixed paraffin embedded ffpe biopsy specimens of a total of 18 gm lesions with immunostaining and real time pcr for ck genome.
Corynebacterium are classified as gram positive non spore forming nonmotile nonpigmented rod shaped diptheroid s 5 and represent a diverse range of microorganisms with equally diverse potential for pathogenicity. Erythrasma is a skin infection characterized by scaly reddish patches in areas where skin surfaces touch such as the groin. The majority of corynebacteria are normal skin flora.
Non diphtheria corynebacteriumspp a component of this flora is commonly viewed as a contaminant but it may be the cause of pneumonia and the frequency with which it causes cap may be underestimated. Corynebacterium kroppenstedtii ck is known as a causative bacterium of gm and identification of ck infection within the lesion should thus be essential for confirming the diagnosis. Kroppenstedtii type strain has revealed a lipophilic lipid requiring lifestyle and a remarkable repertoire of carbohydrate uptake and utilization systems.
Corynebacterium k ɔː ˈ r aɪ n ə b æ k ˌ t ɪər i ə m ˈ r ɪ n is a genus of bacteria that are gram positive and aerobic. 6 however many other members of the genus have been relegated to the role of opportunistic pathogenicity infrequently identified as causative of infection.
